Infection by Marek’s Disease Virus (MDV) is followed by latency, T-cell lymphomas and reactivation. It has significant deleterious effects on chicken health and welfare, with an annual estimated loss close to $2 billion to the global poultry meat and egg production industries.

Campylobacter jejuni is the major causative agent of foodborne gastroenteritis across Europe. Contaminated chicken meat is the main source of infections and hence control of this pathogen is critical to food security in the poultry industry.

Campylobacter jejuni is the main cause of bacterial food-borne disease in the UK and is a global public health priority. Infection and transmission are usually linked with contaminated food or water, with chicken being a major source.

Herpesviruses are large dsDNA viruses that cause widespread, lifelong latent infections in different hosts, through multiple virus-host interactions to create a delicate balance between the virus and the host.
